Very CPU and GPU intensive (my 9800GTX can only do up to 2x without slowdowns).
I hate racing games but this is something else! So much fun, one of my favorite PS2 games and my favorite racing game

Speed: 60 FPS

Bugs:

Purple windows/bottom of cars: Occurs when you boot the game using Boot (full) because it tries to boot in wide screen mode. Fix: Boot the game using Boot (fast)

Black sky: Sky is black in race. Workaround:Boot the game using software mode of GSdx, get in a race, exit back to menu then switch back to hardware renderer by pressing F9. Until you restart PCSX2 again, the sky will be blue, albeit a bit bugged

Very CPU/GPU intensive: Set skipdraw to 2 in GSdx to gain some FPS, but you WILL LOSE reflections/blur effects

White vertical lines: Your game CRC is not included in the GSdx hacks, submit it to the team to get it included. Until that happens, you can get rid of them by setting skipdraw to 3 but you will lose some effects like reflections/blur
